Please note that in such questions, the ":" stands for ratio which in turn stands for divide. Thus, the given expression which is:
will become:
.....(Equation 1)
Now, we know that 3.8 can be rewritten as
. Also, we know that the mixed fraction
can be re-written as:

Using the above two expressions in (Equation 1) we get:


Cross-multiplication gives:




Or c=0.25
Thus, we may write the value of c as either the decimal 0.25 or the fraction
.
Answer:it’s C
729:1
You cube both nine and one to get that
Answer:
The value of x is 6
Step-by-step explanation:
we know that
If two angles are supplementary, then their sum is equal to 180 degrees
so
In this problem
m∠C+m∠E=180°
we have
m∠C=112°
m∠E=(3x+50)°
substitute and solve for x
112°+(3x+50)°=180°
3x+162=180
3x=180-162
3x=18
x=6
Answer:
2(20+5)
2(10+15)
Step-by-step explanation:
When you add 20+5 together you get 25 which is the same to 2(25)
When you add 10+15 together you get 25 which is the same to 2(25)
